FOUNTAIN- PAINTBRUSH.

Specification of Letters Patent.

Patented June 1,, 1920.

Application filed March 6, 1917. 'Serial No. 152,826.

To all whom it may concern:

Be it known that I ROBERT HAINSEY, a

citizen of the United tates, and resident of Altoona, in the county ofBlair and State of Pennsylvania, have invented certain new and usefulImprovements in Fountain-Paintbrushes, of which the following is aspecification.

This invention relates to an improved fountain brush for use with apainting apparatus.

The invention has for its principal object to provide a brush of thischaracter whereby a continuous flow of paint will be had through thebrush, thus facilitating the painting or coatin operation, and obviatmgthe dipping o the brush into a palnt containing receptacle.

Another object of the invention is to provide a novelly constructedbrush, the same being supplied with paint whereby the paint will beevenly distributed onto the bristles thereof, thus preventing streaking.

Another important feature of the invention resides in the provision ofmeans for governing the supply of paint to the bristles of the brush,thereby permitting coats of varying thickness to be applied to objects.

Among other aims and objects of the in-' vention may be recited, theprovision of an apparatus of the character mentionedwith a view tocompactness, and in which the number of parts are few, the constructionsimple, the cost of production small, and efficiency and operation high.

All of the foregoing together with addi-.

tional advantageous details and arrangements of parts of the preferredembodiment of my invention will be clear from the specific descriptionhereinafter contained when read in connection with the accompanyingdrawings forming a part thereof, wherein said embodiment of theinvention is illustrated for the purpose of facilitating a fullunderstanding of the present improvements.

In the drawings Figure 1 is a longitudinal section through the brushconstructed in accordance with the invention;

Fig. 2 is a similar section taken at right angles to Fig. 1; and

Fig. 3 is a disassembled perspective'of the improved cut off means forgoverning the passage of paint to the bristles of the brush. Referringto the drawing in detail 18 designates a hollow brush stock or headhaving a chamber 19 therein which communicates with a way or passage 20extending longitudinally of the handle of said head or stock and throughthis way is introduced a liquid paint to the brush, the outer extremityof the way 20 being fitted with a nipple 21 whereby the free end of aflexible conduit- 5 may be engaged therewith for conveying the liquidpaint from the source of supply to said chamber in the stock or head.

A plurality of longitudinally disposed engagement with the brush. Asubstantially rectangularly shaped opening is formed through the brushhead to one side of the chamber 19 and is adapted to receive therein asimilarly shaped casing 28, the casing being provided with cover plates29 whereby the same is closed and secured in position upon the brush bybolts 30 or the like. A valve 31 is slidably arranged within the easing28 and is provided with a port 31 normally maintained out of register orin closed position with relation to the passage 20 by means of anexpansible coiled spring 32 interposed between one endof the valve andthe adjacent end of the said casing 28. An operating rod 33 extendslaterally from the valve 31 and carries uponits outer end afinger piece34, whereby to facilitate depression of the same, it being understoodthat the said rod extends through a suitable opening formed in the brushhead.

The passage of paint' from the source of there through the tubes 24 intothe brush bristles. By arranging a series of the tubes 24, the paintwill be evenly distributed to the brush bristles and thence, streakingof the object being coated will be prevented. Further, leaking of thepaint from the brush subsequent to the cutting oil of the flow from thesource of supply will be prevented, by reason of the fact that theexpansible coiled spring 32 normally maintains the valve 31 in itsclosed position.

Obviously, the construction shown is capable of considerablemodification and such modification as is within the scope of my claim, Iconsider within the spirit of my in vention.

I claim:

A fountain paint brush including a head having bristles at one end and ahandle at the other end, said head and handle having a .lon 'tudinallydirected passage there;

sides of the casing and attac ed to theh'ead, a valve movable within thecasing and in contact with the cover plates and having a portregistering with the openin s in the casing when in one position, anmeans for actuating said valve. I

In testimony whereof, I afiix my signature hereto.

ROBERT HAINSEY.
